The influence of Omega(b) on high-redshift structure
formation large scale structure of the Universe
2014/12/24
We analyze high-redshift structure in three hydrodynamic simulations that have identical initial conditions and cosmological parameters and differ only in the value of the baryon density parameter, Ωb...
Solar Influence on Nuclear Decay Rates: Constraints from the MESSENGER Mission
stroparticle physics – nuclear reactions – Sun:particle emission
2011/10/12
We have analyzed Cs-137 decay data, obtained from a small sample onboard the MESSENGER spacecraft en route to Mercury, with the aim of setting limits on a possible correlation between nuclear decay ra...
A decay of the ultra-high-energy neutrino $\nu_e \to e^- W^+$ in a magnetic field and its influence on the shape of the neutrino spectrum
the ultra-high-energy neutrino the neutrino spectrum
2011/1/13
The width of the neutrino decay into the electron and $W$ boson in a strong external magnetic field is obtained from the imaginary part of the neutrino self-energy. This result corrects the formulae ...
Influence of nuclear de-excitation on observables relevant for space exploration
nuclear de-excitation observables relevant
2011/1/13
The composition of the space radiation environment inside spacecrafts is modified by the interaction with shielding material, with equipment and even with the astronauts' bodies. Accurate quantitativ...
Context: Hard X-rays from solar flares are an important diagnostic of particle acceleration and transport in the solar atmosphere. Any observed X-ray flux from on-disc sources is composed of direct em...
The influence of collimation on the appearance of relativistic jets
collimation relativistic jets
2011/1/13
The question of the collimation of relativistic jets is the subject of a lively debate in the community. We numerically compute the apparent velocity and the Doppler factor of a non homokinetic jet us...
The influence of inhomogeneities on the large-scale expansion of the universe
influence of inhomogeneities large-scale expansion of the universe
2010/11/12
The evolution of an inhomogeneous universe composed entirely of matter is followed from an early, nearly uniform state until the time when the inhomogeneities have begun to grow large. The particular ...
Quantum Vacuum influence on the evolution of Pulsars
Solar and Stellar Astrophysics (astro-ph.SR) Quantum Physics (quant-ph)
2010/12/23
In this letter we show that Quantum Vacuum Friction (QVF) should play an important role in neutron star evolution. Taking into account this effect we show that magnetars could be understood as a natur...
Cosmography with cluster strong lenses: the influence of substructure and line-of-sight halos
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/22
We explore the use of strong lensing by galaxy clusters to constrain the dark energy equation of state and its possible time variation. The cores of massive clusters often contain several multiply ima...
The Influence of Solar Activity on the Rainfall over India: Cycle-to-Cycle Variations
Solar activity Indian rainfall galactic cosmic rays volcanic or interstellar dust
2010/9/17
We use 130 years data for studying correlative effects due to solar cycle and activity phenomena on the occurrence of rainfall over India. For the period of different solar cycles, we compute the corr...
